  • Flash Player for IPTV

    - by Le Mystique
    Hi All, We have to design a flash player for three video sources of IPTV. Educational videos on the system that can be played on demand. (VOD or Video on Demand local) Streaming videos available on different websites that can be played on demand (VOD or Video on Demand remote) IPTV live streaming video feed Videos from three sources have to be played within single flash player that we need to design. There are 2 basic requirements: For the two VOD types, we have to provide the pause and play functionality. For IPTV, pause and play is not required, However, channel switching time is critically important here. The user should get the program behaviour as close to TV experience as possible. This means channel switching should be fast. To provide this, buffering of video is required for multiple channels. Now the questions is, is this possible? If yes, how? Secondly, what skill set (e.g. action script 3.0 , flash 10) should the flash programmer have to be able to design this? Thirdly is it as simple as making a normal FLV player? Or is it a more complex job?

  • Abstract Factory Method and Polymorphism

    - by Scotty C.
    Being a PHP programmer for the last couple of years, I'm just starting to get into advanced programming styles and using polymorphic patterns. I was watching a video on polymorphism the other day, and the guy giving the lecture said that if at all possible, you should get rid of if statements in your code, and that a switch is almost always a sign that polymorphism is needed. At this point I was quite inspired and immediately went off to try out these new concepts, so I decided to make a small caching module using a factory method. Of course the very first thing I have to do is create a switch to decide what file encoding to choose. DANG! class Main { public static function methodA($parameter='') { switch ($parameter) { case 'a': $object = new \name\space\object1(); break; case 'b': $object = new \name\space\object2(); break; case 'c': $object = new \name\space\object3(); break; default: $object = new \name\space\object1(); } return (sekretInterface $object); } } At this point I'm not really sure what to do. As far as I can tell, I either have to use a different pattern and have separate methods for each object instance, or accept that a switch is necessary to "switch" between them. What do you guys think?

  • Advanced PHP book [closed]

    - by Aaditi Sharma
    I've gone and stumbled across a lot of recommendations for PHP books, including on SO, however could not find a reasonable & convincible answer for this. Is there a really good advanced book for PHP. Background: I've done almost 8 months in PHP. I know the basics. I go through php.net very often. I've played around with Codeigniter, amongst other frameworks. I've been doing JavaScript for almost 2 years, and specifically thank Douglas Crockford for this, I completely changed the way I code JavaScript. I spend a lot of time travelling, and would love to read a book about PHP, that includes the awesome parts and even when something doesn't quite work in PHP. (As a note a lot of previous answers on SO and programmers give varied results.) I have to place an order through a library which has it's limitations. One book that some of experienced PHP programmers could recommend would be helpful. I have gone through http://stackoverflow.com/questions/1711/what-is-the-single-most-influential-book-every-programmer-should-read and http://stackoverflow.com/questions/194812/list-of-freely-available-programming-books, which do NOT have books related to PHP.

  • How do I (quickly) let people know that software I am providing for free is not abandon-ware?

    - by blueberryfields
    As an independent, individual programmer: How do I let people very quickly know that I have not abandoned the software I've written and given away for free? That I am putting in the effort required to maintain and support my software to a professional level? When software written by one or two developers is available for free, or marked as open-source, usually the default assumption is that it's abandon-ware. This is usually a safe assumption - check out the answers to this question if you doubt it: Why do programmers write applications and then make them free?. There are lots of programmers who provide free and/or open-source tools which are not abandon-ware, though. If we're talking about large companies, ie Google, there's no real problem telling the difference between supported, live tools and software, and those which are abandoned or discontinued. A lively git repository isn't quick - users will have to be savvy enough to understand the repository and know where to look for it. Consistent marketing and community management take more time and effort than I can put in on my own. Also, if my software becomes popular/successful, I assume those will grow on their own, and be supported by power users in the community.

  • What's a way to implement a flexible buff/debuff system?

    - by gkimsey
    Overview: Lots of games which RPG-like statistics allow for character "buffs", ranging from simple "Deal 25% extra damage" to more complicated things like "Deal 15 damage back to attackers when hit." The specifics of each type of buff aren't really relevant. I'm looking for a (presumably object-oriented) way to handle arbitrary buffs. Details: In my particular case, I have multiple characters in a turn-based battle environment, so I envisioned buffs being tied to events like "OnTurnStart", "OnReceiveDamage", etc. Perhaps each buff is a subclass of a main Buff abstract class, where only the relevant events are overloaded. Then each character could have a vector of buffs currently applied. Does this solution make sense? I can certainly see dozens of event types being necessary, it feels like making a new subclass for each buff is overkill, and it doesn't seem to allow for any buff "interactions". That is, if I wanted to implement a cap on damage boosts so that even if you had 10 different buffs which all give 25% extra damage, you only do 100% extra instead of 250% extra. And there's more complicated situations that ideally I could control. I'm sure everyone can come up with examples of how more sophisticated buffs can potentially interact with each other in a way that as a game developer I may not want. As a relatively inexperienced C++ programmer (I generally have used C in embedded systems), I feel like my solution is simplistic and probably doesn't take full advantage of the object-oriented language. Thoughts? Has anyone here designed a fairly robust buff system before?

  • I've been told that Exceptions should only be used in exceptional cases. How do I know if my case is exceptional?

    - by tieTYT
    My specific case here is that the user can pass in a string into the application, the application parses it and assigns it to structured objects. Sometimes the user may type in something invalid. For example, their input may describe a person but they may say their age is "apple". Correct behavior in that case is roll back the transaction and to tell the user an error occurred and they'll have to try again. There may be a requirement to report on every error we can find in the input, not just the first. In this case, I argued we should throw an exception. He disagreed, saying, "Exceptions should be exceptional: It's expected that the user may input invalid data, so this isn't an exceptional case" I didn't really know how to argue that point, because by definition of the word, he seems to be right. But, it's my understanding that this is why Exceptions were invented in the first place. It used to be you had to inspect the result to see if an error occurred. If you failed to check, bad things could happen without you noticing. Without exceptions every level of the stack needs to check the result of the methods they call and if a programmer forgets to check in one of these levels, the code could accidentally proceed and save invalid data (for example). Seems more error prone that way. Anyway, feel free to correct anything I've said here. My main question is if someone says Exceptions should be exceptional, how do I know if my case is exceptional?

  • Developing wheel reinventing tendencies into a skill as opposed to reluctantly learning wheel-finding skills? [duplicate]

    - by Korey Hinton
    This question already has an answer here: Is reinventing the wheel really all that bad? 20 answers I am more of a high-level wheel reinventor. I definitely prefer to make use of existing API features built into a language and popular third-party frameworks that I know can solve the problem, however when I have a particular problem that I feel capable of solving within a reasonable time I am very reluctant to find someone else's solution. Here are a few reasons why I reinvent: It takes time to learn a new API API restrictions might exist that I don't know about Avoiding re-work of unfamiliar code I am conflicted between doing what I know and shifting to a new technique I don't feel comfortable with. On one hand I feel like following my instincts and getting really good at solving problems, especially ones that I would never challenge myself with if all I did was try to find answers. And on the other hand I feel like I might be missing out on important skills like saving time by finding the right framework and expanding my knowledge by learning how to use a new framework. I guess my question comes down to this: My current attitude is to stick to the built-in API and APIs I know well* and to not spend my time searching github for a solution to a problem I know I can solve myself within a reasonable amount of time. Is that a reasonable balance for a successful programmer? *Obviously I will still look around for new frameworks that save time and solve/simplify difficult problems.

  • How do programers balance the upper or lower case style to name file or folder between work and life?

    - by sojyq
    I am a programmer from China. And I like to use English words to name my files and folders Whether it is for work or life. For example, suck as Movie, Work, QtProjects, Music and so on.And I keep the habit of initial the first letter for file name or folder name in Windows. But now I work on Ubuntu, and I found that all file name and folder name are lowercase in addition to the default folder such as Music, Movie and so on. And then I realize that in Linux world, most peoloe like to use all lowercase to name their files and folders for two reasons (1. Linux is Case sensitive. 2. It is fast for shell command.). And after work, when I switch from Linux to Windows, I confuse to use all lowercase or the first letter uppercase style to name my files in Windows. I'm caught in a dilemma. I think that all lowercase is more efficiency but the first letter uppercase is more readable. I thought for a long time and want to come up with a good answer to blance the two style name conversion. But I failed. I want to ask you that how you balance the uppercase or lowercase habbit in Windows, Mac, Linux between work and personal life style? Thank you very much! (My current solution is that when I am in Linux, I use all lowercase for files and folders, but when I am in Windows and Mac OS X, I couldn't find a good reason to convince me to use all lowercase ( I think in Windows and Mac OS X, the first letter uppercase style for me is more readable and beautiful).

  • What are some good resources for creating a game engine in XNA?

    - by Glasser
    I'm currently a student game programmer working on an indie project. We have a team of eleven people (five programmers, four artists, and two audio designers) aboard, all working hard to help design this game. We've been meeting for months now and so far we have a pretty buffed out Game Design Document as well as much audio/visual concept art. Our programmers are itching to progress on our own end. Each person in our programming team is well versed in C++, but is very familiar with C#. We have enough experience and skill that we're confident that we will be successful with our game, and we're looking to build our own game engine in XNA as it seems like it would be worth our time and effort in the end. The game itself will be a 2D beat 'em up style game to be released over xbox live and the PC. It's play style will be similar to that of Castle Crashers or Scott Pilgrim vs The World. We want to design the game engine to allow us to better implement our assets into the game as well as to simplify the creation of design elements/mechanics. Currently between our programmers, we have books such as "XNA 4.0" and "Game Coding Complete, Third Edition," but we'd still like more information on both XNA and (especially) building a game engine from scratch. What are any other good books, websites, or resources we could use to further map out and program our game engine?

  • Do Great Work

    - by user12601034
    Have you ever attended an online conference and actually had a desire to attend all of it?? Yesterday I attended the first day of the Great Work MBA program, sponsored by Box of Crayons and hosted by Michael Bungay Stanier. The topic of the day was “Grounding Yourself,” and the day featured five speakers on five different topics. I have to admit that I started the first session with kind of a “blech” feeling that I didn’t really want to participate, but for some reason I did. So I listened to the first session, and I was hooked. I ended up listening to all of the sessions for the day, and I had some great take-aways from the sessions – my highlights included: The opposite of bravery isn’t fear, it’s settling. In essence, you need to be brave in order to accomplish anything. If you’re settling, you’re not being brave, and your accomplishments will likely be lackluster. Bravery requires confidence and permission. You need to work at being brave by taking small wins, build them up and then take slightly larger risks. Additionally, you need to “claim your own crown.” Nobody in the business world is going to give you permission to be a guru in X – you need to give yourself permission to become a guru in X and then do it. Fall in love with obstacles. Everyone is going to face some form of failure. One way to deal with this is to fall in love with solving the puzzle of obstacles. You don’t have to hit it if you can go around it. Understanding purpose brings out the best in people and the best people. As a leader, drawing in people who are passionate and highly motivated about their work creates velocity for your organization. Being clear about purpose is the first step in doing this. You must own your own story. Everything about you creates a “unique you” that is distinct from everyone else. As you take ownership of this, it becomes part of your strength. It’s not a strength if you’re running away from it. Focus on what’s right. Be aware of your tendency to interpret a situation a certain way and differentiate between helpful and unhelpful interpretations. Three questions for how to think differently: 1) Why? 2) Who says so? 3) What would happen if? These three questions can help you build alternative perspectives and options that can increase resiliency. Even though this first day was focused on “Grounding Yourself,” I see plenty of application in the corporate environment for both individuals and leaders of teams. To apply these highlights to my work environment, I would do the following: Understand the purpose – of my company, of my team and of my role on the team. If I know the purpose, I know what I need to bring to the table to make me, my team and my company successful. Declare your goals…your BEHAGS (big, hairy, audacious goals).Have the confidence to declare what you and/or your team is going to accomplish.Sure, you might have to re-state those goals down the line, but you can learn from that as well. Get creative about achieving your goals.Break down your obstacles by asking yourself what is going to stop you from achieving your goals and then, for each obstacles, ask those three questions:Why?Who says so? What would happen if? Focus on what’s right.I had a manager who asked us to write status reports every week.“Status” consisted of 1) What did I accomplish; 2) What will I accomplish next week; 3) How can my manager help me.The focus on our status report was always “what’s right”(“what’s wrong” was always a conversation at the point in time it was needed). I’m normally a skeptic of online webcasts/conferences, and I normally expect to take away maybe one or two ideas. I’m really glad, however, that I took the time to listen to all of the sessions yesterday, and I hope that my take-aways inspire you to think about how you might do great work also. --

  • How to deal with the need to know multiple programming languages? When to stop learning new languages?

    - by Raphael
    I am a relatively young programmer. I am 23 and I have been programming professionally for about 5 years. As most programmers I started with C, learned some x86 assembly for fun and then I found C++ which turned out to be my greatest passion in the programming world. Programming with C and C++ forces you to learn platform specific APIs, libs and frameworks all of each requires constant study and experimentation. After some time I had to move on to Java and C# as the demand on my region is basically for these languages. With these languages I entered the world of web development and then I had to learn javascript. Developing for the .NET Framework was exciting at first but I constantly felt as I was getting tied up by Microsoft (and of course the .NET Framework was driving me away from Linux). For desktop development I could do pretty much everything I did with .NET using C++ with Qt but for web development I had to look for an alternative. Quickly I found Django and then I proceeded to learn Python so I could use Django. Nowadays I am learning iOS development with Objective-C. So far it was pretty much easy to learn all these languages (C++ trained me well) but I am worried that someday I won't be able to keep track of them all. Just to clarify. The only languages I learned cause I had to were C# and Java. All of the others I learned for fun, because I love programming and learning new things. Also I like to keep my skills sharp on desktop, web and mobile development. My question is: How do you keep track of multiple programming languages? (I mean, keep track of changes to these languages and keep your skills sharp) and: Is there such a thing as enough programming languages?

  • Website Hosting/Registration [closed]

    - by Ricko M
    Possible Duplicate: How to find web hosting that meets my requirements? I am planning to launch a website down soon. I wanted to know what solutions are available for hosting and registration. Starting with domain registration. Any site you have used/preferred ? I am considering either godaddy or 123reg. Does it even make any difference which you choose? Is there any fine print i need to worry about. I am based in UK , not sure if that helps in resolving any issues if encountered. Does my hosting need to be done at the site i purchased my registration? If not , will there be any transfer fees if i change my hosting? Can I just register the name now and worry about hosting later? At the moment, I plan to have it up and running using either some sort of a tool or a template and perhaps put the bells and whistles down the line. I understand 123 has its own builder tool available, There are a few solutions suggested like wordpress,drupal & jhoomla... I am a C++ developer , not a web programmer, but I do feel the need to open the hood up and make changes if i see fit. So I guess I am looking for a solution where I can easily drag-drop widgets I need and when the time comes customize it. Which CMS would you recommend. Extras: What extras do you need to get , I was suggested to get hold of whois privacy to keep the spambots away, anything else you guys would recommend I keep my eyes open before I sign the dotted line.

  • Graduating soon with a computer science degree, but have unique circumstances [closed]

    - by Donnie
    I joined the Navy in 1998, and was admitted into Nuclear Power Training. I got my electrician's mate certificate, but was put on medical hold when I was in Nuclear Power Training. I was sent to the Naval Hospital, and received a medical (honorable) discharge in the middle of 2000. I decided to stay at home and raise my son, and my girlfriend worked. a few years ago, I decided that I want to work as a programmer, so I went to college and will soon be graduating with a degree in computer science. I hope to finish with a relatively high GPA, 3.8 or 3.9. My question is this: How much, if any, of my Navy experience should I put on my resume? And how do I explain my nine year gap as a stay at home dad? Do I even try to explain it? I know recent college graduates typically have no experience, but obviously I'm not the typical college graduate. Will my long absence from working, or my relatively short duration in the Navy hurt my chances? Should I just put the college on my resume, and hope that HR thinks I'm younger than I am? Obviously, then, my age would show at the interview and there would be questions. Any help is appreciated.

  • Am I programming too slow?

    - by Jonn
    I've only been a year in the industry and I've had some problems making estimates for specific tasks. Before you close this, yes, I've already read this: http://programmers.stackexchange.com/questions/648/how-to-respond-when-you-are-asked-for-an-estimate and that's about the same problem I'm having. But I'm looking for a more specific gauge of experiences, something quantifiable or probably other programmer's average performances which I should aim for and base my estimates. The answers range from weeks, and I was looking more for an answer on the level of a task assigned for a day or so. (Note that this doesn't include submitting for QA or documentations, just the actual development time from writing tests if I used TDD, to making the page, before having it submitted to testing) My current rate right now is as follows (on ASP.NET webforms): Right now, I'm able to develop a simple data entry page with a grid listing (no complex logic, just Creating and Reading) on an already built architecture, given one full day's (8 hours) time. Adding complex functionality, and Update and Delete pages add another full day to the task. If I have to start the page from scratch (no solution, no existing website) it takes me another full day. (Not always) but if I encounter something new or haven't done yet it takes me another full day. Whenever I make an estimate that's longer than the expected I feel that others think that I'm lagging a lot behind everyone else. I'm just concerned as there have been expectations that when it's just one page it should take me no more than a full day. Yes, there definitely is more room for improvement. There always is. I have a lot to learn. But I would like to know if my current rate is way too slow, just average, or average for someone no longer than a year in the industry.

  • When must I turn my business idea into a formal Company? [closed]

    - by Sony Santos
    I'm a programmer, I have an idea, I know how to implement it, it will be a website, and that site will be my business. My question is very basic: where in timeline must I register my business as an official Company (ie, according Government laws)? Here there are some options to debate or to help answer me: Now - or as soon as I have the idea; When looking for investors (e.g., when a prototype or business plan is ready); When implementing the website; At site's launch; I must launch the website as a personal informal business and, when the business gets success and turns into a more solid and self-running one, only then I must formalize it; It doesn't matter; I can create the company when I want. Nobody talks about that. If I just have an idea, must I run into an office to create a Company? I don't think so. When I'll look for investors, the Company must to pre-exist? Or will the Company be formed with the investor? I'm looking for a generic, country-independent answer, but may the answer for your country can be useful to me. I'm Brazilian, and I believe that the country doesn't matter to this question. (Sorry if this is off-topic, but I coudn't find a batter stackexchange site to ask this.)

  • Windows Physical Direct Memory Mapping

    - by chrisjleaf
    I'm a bit disappointed there is almost no discussion of this no matter where I look so I guess I'll have to ask. I'm writing a cross platform memory bench marking application which requires direct physical address mapping rather than virtual addressing. EDIT The solution would look something like the Linux/Unix system calls: int fd = open("/dev/mem", O_RDONLY); mmap(NULL, len, PROT_READ, MAP_SHARED, fd, PHYSICAL_ADDRESS_OFFSET); which will require the kernel to either give you a virtual page mapping to the desired physical address or return that it failed. This does require supervisor privileges but that is ok. I have seen a lot of information about shared memory and memory mapped files but all of these reside on disc and are thus not really useful when I'm trying to make a system dependent read. It is very similar to writing an IO driver although I do no need write permissions to the physical address. This site gives an example of how to do it on a driver level using the Windows Driver Kit: NT Insider: Sharing Memory between drivers and applications This solution would probably require Visual Studio which currently I do not have access to. (I have downloaded the WDK api but it complained about my use of GCC for Windows). I'm traditionally a Linux programmer so I'm hoping there might be something really simple I'm missing. Thanks in advance if you know something I don't!

  • Open Source Project all dressed up but nowhere to go...

    - by Calanus
    Over the past 2 years myself and a colleague have built an online statistical analysis application using a mixture of silverlight, wcf and R. I (a c# programmer) wrote all the silverlight and wcf stuff whilst my colleague (a statistician) came up with the stats algorithms and wrote the R code. Now we think that this app is fairly unique - a rich gui online statistics application that is much more intuitive than all the other online stat apps that I've seen. But despite this we don't really know where to go with the project, mainly for the following reasons: 1) Its fairly complicated stuff - without the mix of programing and stats skills it would be difficult for anyone to "get into" the project and contribute. 2) We are stalled by a lack of a proper place to host the site. Currently it sits on the family windows 7 media centre, not exactly the best place to host it as it could interfere with the missus trying to watch Corrie/Friends/Oprah etc. Soo, anyone got any ideas on how to move forward with this? I guess that my strength is programing not marketing so despite working hard at this for the past couple of years I feel that I've reached a dead end! Also, does anyone know of any free windows hosting for open source projects? If I could find a proper place to put the app I might feel re-energised about the whole thing. The source code is on codeplex at: http://silverstats.codeplex.com, whilst the app is currently hosted at http://silverstats.co.uk

  • General List of Common Programming Errors

    - by javamonkey79
    As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!

    I have several years of software development experience, but I am not a keen and adroit programmer, to perform better I need helping hands. Recently I engaged in an ERP project. For this project want a very effective structure, which will be easily maintainable and have no compromise about performance issue. Below structures are now present in my old projects. Entity Layer BusinessLogic Layer. DataLogic Layer UI Layer. Bellow picture describe how they are internally connected. For my new project want to change my project structure, I want to follow below steps: Core Layer(common) BLL DAL Model UI Bellow picture describe how they are internally connected. Though goggling some initial type question’s are obscure to me, they are : For new project want to use Entity framework, is it a good idea? Will it increase my project performance? Will it more maintainable than previous structure? Entity Framework core disadvantages/benefits are? For my project need help to select best structure. Will my new structure be better than the old one?

  • Storing data offline with javascript

    - by Walker
    My question is about storing data offline and potentially whether I will need to bring in an outside programmer or could this be learned within a few weeks? The website I am working on will have an interface where users will login and go through a series of quizzes in the form of checkbox, drop down menus, and others. Each page/quiz area could have 20-100 total checkboxes in a series of 3-5 rows because of the comprehensive nature of course. This I can do - I know how to code the quiz and return a correct or incorrect answer based on each individual checkbox and present a cumulative score (ie: you got 57% correct). The issue lies in the fact that I would like to save the users results and keep them informed of their progress. When they complete all of the quizzes, I would like to have a visual output of their performance in each area. Storing the output from their results offline is where I think I may run into a problem with my lack of coding experience. I would also like to have a sidebar with their progress of each section (10-15) with a green percentage completion bar or a % correct which would draw from this. I have never had to code something that stores information like this offline - so back to my question - would it be better to learn the language needed or bring in a coder/developer for the back end stuff.

  • How to manage Areas/Levels in an RPG?

    I'm working on an RPG and I'm trying to figure out how to manage the different levels/areas in the game. Currently I create a new state (source file) for every area, defining its unique aspects. My concern is that as the game grows the number of class files will become unmanageable with all the towns, houses, shops, dungeons, etc. that I need to keep track of. I would also prefer to separate my levels from the source code because non-programmer members of the team will be creating levels, and I would like the engine to be as free from game specific code as possible. I'm thinking of creating a class that provides all the functions that will be the same between all the levels/areas with a unique member variable that can be used to look up level specifics from data. This way I only need to define level/area once in the code, but can create multiple instances each with its own unique aspects provided by data. Is this a good way to go about solving the issue? Is there a better way to handle a growing number of levels?

  • Why job postings always looking for "rockstars?"

    - by Xepoch
    I have noticed a recent trend in requesting programmers who are rockstars. I get it, they're looking for someone who is really good at what they do. But why (pray) make the reference to a rockstar? Do these companies really want these traits as a real rockstar? Party all night and wake up to take care of quick business in the morning? Substance abuse, Narcissism with celebrity, Compensation well exceeding their management, Excellent at putting on a short-lived show, Entertainment instead of value, 1 hit (project) wonders or single-genre performers, Et cetera What is wrong with Senior or Principal Software Engineer who has an established and proven passion for the business? Rather do we mean quite the opposite, someone who: rolls up the sleeves and gets to work, takes appropriate direction and helps influence teams, programs in lessons' learned and proper practices, provides timely communication to the whole team, can code and understand multiple languages, understands the science and theory behind computation, Is there a trend to diversify the software engineering ranks? How many software rockstars can you hire before your band starts breaking up? Sure, there are lots of folks doing this stuff on their own, maybe even a rare few who do coding for show, but I wager the majority is for business. I don't see ads for rockstar accountants, or rockstar machinists, or rockstart CFOs. What makes the software programmer and their hiring departments lean towards this kind of job title?

  • Is it possible to procure venture capital based on in-progress ideas? [migrated]

    - by Clay Shannon
    I hope this is not the wrong forum for this question, but I can't find one in the Stack Exchange "family" that would be more appropriate. I have ideas for two web sites which I think will be quite popular (they are totally unrelated to each other). I am a programmer, and a "creative" (photographer, author, musician). So I have the "vision" as well as the technical know-how to bring these websites into being. My "problem" is that I'm champing at the bit to complete them, and don't have much time to work on them (being employed fulltime, etc.) If I continue to work on them in my so-called spare time, it will probably be a year or more before they are both done. If I was in a position to work on them fulltime (IOW, if I had a "silent partner" willing to invest enough money that I could quit my job), I could have them complete in about three months. I would be willing to partner with somebody or some group who would back me financially in this way. My vision/work combined with their monetary investment could bring about "great things" or at least moderately great things. I know you can "crowd fund" startups and so on, but for that you need to expose your idea. My ideas are not something I would want to make public, as somebody might "steal" them. I'm willing to discuss them with serious individual potential investors, though (provided they were willing to sign a non-disclosure agreement). Does anybody have any recommendation on how I might find a suitable partner[s] for this/these ventures?

  • Estimate angle to launch missile, maths question

    - by Jonathan
    I've been working on this for an hour or two now and my maths really isn't my strong suit which is definitely not a good thing for a game programmer but that shouldn't stop me enjoying a hobby surely? After a few failed attempts I was hoping someone else out there could help so here's the situation. I'm trying to implement a bit of faked intelligence when the A.I fires it's missiles at a target in a 2D game world. By predicting the likely position the target will be in given it's current velocity and the time it will take the missile to reach it's target. I created an image to demonstrate my thinking: http://i.imgur.com/SFmU3.png which also contains the logic I use for accelerating the missile after launch. The ship that fires the missile can fire within a total of 40 degree angle, 20 either side of itself, but this could likely become variable. My current attempt was to break the space between the two lines into segments which match the targets width. Then calculate the time it would take the missile to get to that location using the formula. So for each iteration of this we total up the values and that tells us the distance travelled, ad it would then just need compared to distance to the segment. startVelocity * ((startVelocity * acceleration)^(currentframe-1) So for example. If we start at a velocity of 1f/frame with an acceleration of 0.1f the formula, at frame 4, would be 1 * (1.1^3) = 1.331 But I quickly realized I was getting lost when trying to put this into practice. Does this seem like a correct starting point or am I going completely the wrong way about it? Any pointers would help me greatly. Maths really isn't my strong suit so I get easily lost in these matters and don't even really know a good phrase to search for with this. So I guess in summary my question is more about the correct way to approach this problem and any additional code samples on top of that would be great but I'm not averse to working out the complete code from helpful pointers.
